Book Description
Several models have been developed to describe the diffusion transport in multicomponent polymeric coatings using Bearman s friction factor theory. In this work, all the available models have been tested against measured concentrations at several depths and time in given coating using confocal laser Raman spectroscopy. Experimental results shows that none of the model is able to predict complete drying behavior of multicomponent polymeric coatings. A new method has been developed to find near optimum drying condition for binary coating. Method has been tested for multizone dryers. It needs only a drying code and obviates the need of optimization subroutine. Non-Fickian trasnport has been observed experimentaly and it is first work which shows experimental proof of non-Fickian drying in polymeric coatings which turns glassy at drying conditions.

Book Description
This book addresses the general aspects of current knowledge of multicomponent transport in hydrophylic and moderately hydrophylic polymers. The first part of the book presents the physical and mathematical models which have been developed in order to predict the behavior of systems consisting of polymer, water and low-molecular solutes. The second half addresses different transport devices for controlled delivery and how the principles reported in the first part could be applied to the regulations of kinetics and the rate of transport of water and solutes. Major applications of polymer systems for controlled release in medicine, agriculture, and in industry are also described.

Book Description
Multicomponent Diffusion discusses the multicomponent diffusion of the three phases of matter. The book is comprised of nine chapters that cover studies of multicomponent diffusion and mass transfer with an emphasis on the chemical characteristics responsible for multicomponent diffusion. Chapter 1 provides an introductory discourse about multicomponent diffusion. Chapter 2 discusses binary diffusion, while Chapter 3 covers multicomponent flux equation. The measurement of ternary diffusion and the estimation of ternary diffusion coefficients are also explained in the book. A chapter then covers the interacting systems, and the subsequent chapter talks about membranes without mobile carriers. The text also discusses carrier-containing membranes and the multicomponent mass transfer. The book will be of great use to researchers and professionals whose work requires a good understanding of multicomponent diffusion.

Book Description
The book offers an in-depth review of the materials design and manufacturing processes employed in the development of multi-component or multiphase polymer material systems. This field has seen rapid growth in both academic and industrial research, as multiphase materials are increasingly replacing traditional single-component materials in commercial applications. Many obstacles can be overcome by processing and using multiphase materials in automobile, construction, aerospace, food processing, and other chemical industry applications. The comprehensive description of the processing, characterization, and application of multiphase materials presented in this book offers a world of new ideas and potential technological advantages for academics, researchers, students, and industrial manufacturers from diverse fields including rubber engineering, polymer chemistry, materials processing and chemical science. From the commercial point of view it will be of great value to those involved in processing, optimizing and manufacturing new materials for novel end-use applications. The book takes a detailed approach to the description of process parameters, process optimization, mold design, and other core manufacturing information. Details of injection, extrusion, and compression molding processes have been provided based on the most recent advances in the field. Over two comprehensive sections the book covers the entire field of multiphase polymer materials, from a detailed description of material design and processing to the cutting-edge applications of such multiphase materials. It provides both precise guidelines and general concepts for the present and future leaders in academic and industrial sectors.

Book Description
Recent years have witnessed the sheer growth of macromolecular concepts and nanotechnology-based innovations in polymer science. Processing and Characterization of Multicomponent Polymer Systems is a collection of contributions from materials science experts across the globe. The fabrication and characterization of polymeric systems are still important in the study of materials science, and the quality measurements of newly designed polymeric stuffs demand systematic and new characterization protocols. The volume highlights some of the latest innovations and principles of nanostructured polymeric materials and polymer nanocomposites. It is devoted to novel architectures at the nano-level with an emphasis on new synthesis and characterization methods. Organized into several sections, the chapters cover a selection of topics on: Biocomposites and nanocomposites Interpenetrating polymeric networks and nanostructured materials Theoretical protocols for polymers and clusters Special topics in polymer processing and polymer coating. This survey will be an important resource for those involved in the field of polymer materials design for advanced technologies, including scientists, engineers, and budding researchers working in the area of polymer science and nanotechnology.

Book Description
In August, 1996, the ACS Division of Polymeric Materials: Science and Engineering hosted a symposium on Interfacial Aspects of Multicomponent Polymer Materials at the Orlando, Florida, American Chemical Society meeting. Over 50 papers and posters were presented. The symposium proper was preceded by a one-day workshop, where the. basics of this relatively new field were developed. This edited book is a direct outcome of the symposium and workshop. Every object in the universe has surfaces and interfaces. A surface is defined as that part of a material in contact with either a gas or a vacuum. An interface is defined as that part of a material in contact with a condensed phase, be it liquid or solid. Surfaces of any substance are different from their interior. The appearance of surface or interfacial tension is one simple manifestation. Polymer blends and composites usually contain very finely divided phases, which are literally full of interfaces. Because interfaces are frequently weak mechanically, they pose special problems in the manufacture of strong, tough plastics, adhesives, elastomers, coatings, and fibers. This book provides a series of papers addressing this issue. Some papers delineate the nature of the interface both chemically and physically. The use of newer instrumental methods and new theories are described. Concepts of interdiffusion and entanglement are developed. Other papers describe state-of-the-art approaches to improving the interface, via graft and block copolymers, direct covalent bonding, hydrogen bonding, and more.
